A 42-year-old woman from rural Rajasthan presents with a 4-month history of progressive lower back pain and bilateral lower limb weakness. Examination reveals paraplegia (Grade 2/5 bilaterally), sensory loss below L4, and a palpable kyphotic deformity at the lumbosacral junction. She has a history of pulmonary TB treated 2 years ago. Plain radiographs show collapse of L4 and L5 vertebral bodies with loss of disc space height. MRI shows cord compression at L4–L5 from a combination of vertebral collapse, granulation tissue, and a posterior epidural mass. Which of the following is the most appropriate next step in management?

Explanation

## Management of Pott Disease with Neurological Deficit **Key Point:** The management of spinal tuberculosis with neurological compromise is primarily **medical (anti-tuberculous therapy)** with **selective surgical intervention** based on response and severity. Early paraplegia (onset < 18 months) typically responds well to ATT alone; late-onset paraplegia may require surgery. ### Classification of Pott Paraplegia | Type | Onset | Mechanism | Prognosis with ATT | Surgical Indication | |------|-------|-----------|-------------------|--------------------| | **Early-onset** | < 18 months | Active inflammation, granulation tissue, abscess | Excellent (70–90% recovery) | Reserved for failed medical therapy | | **Late-onset** | > 18 months | Fibrosis, bony ankylosis, instability | Fair (40–50% recovery) | More likely needed | | **Healed disease** | Years after cure | Severe kyphosis, instability | Poor | Often requires surgery | **High-Yield:** This patient has **early-onset paraplegia** (4-month history during active disease). The standard approach is: 1. **Initiate anti-tuberculous therapy immediately** — 4-drug regimen (HRZE) for 2 months, then HR for 7 months 2. **Assess neurological response at 4–6 weeks** — most patients show improvement with ATT alone 3. **Reserve surgery for:** - No neurological improvement after 4–6 weeks of ATT - Progressive neurological deterioration despite ATT - Severe kyphosis (>60°) with instability - Abscess requiring drainage - Bony reactivation or late-onset paraplegia ### Surgical Options (When Indicated) ```mermaid flowchart TD A[Pott Disease with Paraplegia]:::outcome --> B{Early or Late Onset?}:::decision B -->|Early < 18 months| C[Start ATT]:::action B -->|Late > 18 months| D[ATT + Consider Surgery]:::action C --> E{Improvement at 4-6 weeks?}:::decision E -->|Yes| F[Continue ATT, Monitor]:::action E -->|No| G[Surgical Decompression]:::action D --> H{Severe Kyphosis or Instability?}:::decision H -->|Yes| G H -->|No| I[Trial of ATT]:::action G --> J{Anterior or Posterior Compression?}:::decision J -->|Anterior| K[Anterior Corpectomy + Fusion]:::action J -->|Posterior| L[Laminectomy + Fusion]:::action ``` **Clinical Pearl:** Anterior vertebral body involvement (as in this case) with anterior cord compression is best approached via **anterior corpectomy and strut grafting** if surgery becomes necessary. However, surgery is NOT the first-line intervention in early-onset paraplegia. **Warning:** Do NOT perform immediate surgery in early-onset paraplegia without a trial of ATT. Approximately 70–90% of early-onset cases resolve with medical therapy alone. Premature surgery increases morbidity and is not evidence-based. ### Monitoring During ATT - **Clinical assessment** — weekly for first month, then monthly - **Imaging** — baseline MRI, repeat at 3 months and 6 months to assess inflammation and cord compression - **Neurological grading** — use Frankel scale or ASIA score for objective documentation - **Drug compliance** — ensure adherence to 9-month regimen **Tip:** In NEET PG exams, remember: **Early paraplegia = ATT first; Late paraplegia = ATT + Surgery likely needed.** This patient's 4-month history is early-onset, so ATT with reassessment is the correct approach.
